BLANK FOR PAPER BOXES.

SPIEGIFIGATION formingpart of Letters Patent No. 693,169, dated February 11, 1902. Application filed September 12, 1899., Serial No. 730,232. (No model.)

To all whom i2; may concern:

Be it knownthat LHARRYB. SMITH, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Blanks for Paper Boxes, of whichthe following is a specification.

This invention relates to certain new-and useful improvements in boxes having ornamental corners and in box-blanks from which said boxes may be formed, and more particularly to blanks for making paper boxes.

It is one object of the invention to provide an inexpensive and readily-constructed blank for forming paper boxes having cut-away corners formed at an angle to the sides and ends of the box, the bottom, sides, and ends of the box being formed from a single blank and the flaps or wings forming said ends and sides being constructed in such manner as to form when folded up and secured in position a smooth unbroken surface around the entire outer edge of the box, no overlapping parts whatever being presentin-the structure,which constitutes a prominent characteristic of the box.

There exists in the trade at the present time with overlapping portions or edges at the corners, which render the latter uneven, cumbersome, or bulky, prevent the top or cover of the box from forming a tight joint at the corners of the latter, and otherwise detract generally from the neatness and desirability of the box.

The present invention therefore comprises a box-blank made from paper, cardboard,

or other'suitable-material and' consisting of a body portion of any desired shape, having its corners cut away at an angle to the sides and ends of that portion of the blank designed to form the bottom of the box and provided with integral side and end wingsor flaps, which latter are cut away at their ends to such a degree or extent that the combined length of all of said wings or flaps will not exceed the distance around the circumference of the said bottom or body portion, so that when they are folded up into position to form the box the adjacent ends of said wings or flaps will practically abut each other to form a close fit, but will not overlap one another, thus producing a smooth, continuous, and unbroken surface around the edges or circumference of the box.

The invention further comprises'a novel form of box formed from a blank having a body portion with cut-away corners of any desired shape or configuration and integral side and end wingsor flaps, said wings or flaps being folded up into position so that the adjacent edges thereof will abut but not overlap to provide a flush or smooth joint and then secured together by suitable fastening means, as hereinafter described in detail.

In order to enable others to construct boxblanks or boxes in accordance with my invention, lwill describe the same in detail, referones being had for this purpose to the accompanying drawings, wherein- Figure 1 is a plan viewof one of my improved box-blanks. Fig. 2 is a perspective view of onecorner of a box formed from the improved blank shownin Fig. 1. Fig. '3 isa plan view of one corner of a slightly-modified form of blank. Fig. 4; is a perspective view of one corner of a box formed from the blank shown in Fig. 3. Fig. 5 is a plan view of a blank similar to that shown in Fig. 1,but illustrating a slightly-modified manner of forming the side and end flaps or wings. Fig. 6 is a perspective view of one corner of a box formed from the blank shownin Fig. 5. Fig.

7 is a perspective view of a box made according to my invention from the blank shown in Fig. 1, the side and end flaps being secured by a metal corner-clip. Fig. 8 is a-similar view of one corner of a box, showing the abut ting edges of the flaps secured together by a short strip of paper pasted to said flaps. Fig.

Beferrin g to the drawings,the refercncenu IOO - taugular in shape; but I wish it understood signed to form the bottom of the box, as indimeral 1 indicates the body of the blank, which in the present instance isshown as beingrec that I do not confine myself to any particular shape of blank, for obviously the shape and general outline of the blank may be varied at will withoutdeparting from myinvention, the novel features of which I will now describe.

Referring to Fig. 1, the corners of the blank 1 are chamfered, beveled, or cut away at an angle to the sides and ends of that portion decated at 2, and the sides and ends of the blank are provided with integral flaps or wings 3 3 and 4 4, respectively, the body of the blank being scored, cut, or creased along the lines 5 5 and 6 6, where the said end and said flaps or wings join the said body of the blank, to facilitate the folding or upward bending of said flaps or wings during the formation of the box. The opposite free ends 7 and 8 of the side and end flaps, respectively, are out offin such manner that the maximum length of each flap will be slightly less than the corresponding width and length, respectively, of the body portion of the blank, or, in other words, the combined length of allof said flaps does not exceed the circumference of the said body portion, whereby when the said flaps are folded up into the position shown in Fig. 2 to form the box and the free ends7 and 8 of said flaps are bent around the chamfered or beveled corners 2 the adjacent edges of the free ends of said flaps willjust meet and abuteach other to form a close joint or fit, but will not overlap, and this constitutes an important and prominent characteristic of the invention. To insure the ends of the flaps being bent, so as to accurately conform to the chamfered or beveled corners and to facilitate such bending the said flaps are scored, cut, or creased trans versely on the lines 9 9 and 1010, such scored, cut, or creased lines extending from the outer edges of the flap to the points where the free ends of the latter join the body of the blank.

After the wings have been folded up into position to form the box they can be retained in such position in any suitable manner, as by metal corner-clips, short strips of paper pasted or glued to the corners, or by a surrounding strip of covering-paper, which will be pasted entirely around the outer edge of the box, as clearly shown in Figs. 7, 8, and 9, and owing to the fact that a clean flush joint is formed at the chamfered or beveled corners, no overlapping parts being present, a smooth unbroken surface is provided, which not only adds greatly to the nealness and attractiveness of the box, but also permits the cover or top to form a tightjoint with the box at every point.

In Figs. 3 and t of the drawings I have illustrated a slightly-modified form of blank, the corners of which instead of being chamfered or beveled off on a straight line, as shown in Fig. 1, are each chamfered or cut away at a compound angle-that is to say,

while each corner is cut away at an angle to the sides and ends of the body portion of the blank, instead of being cutaway on a straight line it is cut away on two straight lines 11 11, formed at an obtuse angle to one another, the apex of which lies equidistant between the points where the ends of the flaps 3 and 4t join the body of the blank; otherwise the construction of the blank is the same in all respects as that before described, and hence when the side and end flaps are folded up into position to form the box the free ends 7 and 8 of the side and end flaps will conform to the angular sides 1] ll of the corners, and their adjacent edges will just meet and abut each other at the apex of the angle formed by the sides ll 11 to form a close joint or fit in the manner before described.

In Figs. 4 and 5 I have illustrated a slightly further modified manner of constructing the blank. As shown in Fig. 4, the blank is formed in precisely the same manner as the blank shown in Fig. 1, excepting that instead of cutting off the opposite ends of the side and end flaps 3 and at in such manner that each will project beyond the points intersected by the chamfered or beveled corners only one end of each flap shall project in such manner, as indicated at Wand S, the opposite end 12 being cut off at the point where the flap is intersected by the chamfered or beveled corner, the relative proportions of the flaps and body of the blank, nevertheless, being still retained in such manner that the combined length of all the side and end flaps shall not exceed the circumference of the body portion of the blank, whereby when the flaps are folded up into position toform the box the free ends 7 and 8 will conform to the chamfered or beveled corners of the blank and their vertical edges will just meet and abut the corresponding edges 12 of the adjacent flaps in the same manner and for the purpose before described.

In each of the different forms of blanks shown and described the flaps are scored, cut, or creased transversely, as shown, to facilitate folding the free ends of the flaps and to cause them to accurately conform to the chamfered or beveled corners of the blank, such lines of scoring in each instance being formed at the points where the ends of the chamfered or beveled corners join the flaps.

In Figs. 7, S, and 9 of the drawings I have shown several ways of securing the abutting edges of the flaps in position for the formation of the box, as heretofore briefly alluded to. One manner of means comprises a metal clip 13, having openings punched therefrom upon opposite sides, leaving sharp edges or burs projecting therefrom which are forced intothe material of the flaps and clenched upon the inside of the box, as best seen in Fig. 7. Then applied, the fastening-clips cover the joint formed by the abutting edges of the flaps and hold the parts in a close and firm manner.

The metal clip herein shown is the one I prefer to employ; but I do not wish to be understoodas limiting myself to such form of clip, for it will be obvious that any clip having prongs or burs extending therefrom may be equally as well employed.

Instead of using the metal clips shown in Fig. 7 I may paste or glue short strips of covering-paper 14 over the abutting edges of the flaps at-the corners, as illustrated in Fig. 8, or I may employ a surrounding strip of covering-paper 15, which will be pasted or glued entirely around the outer edge or circumference of the box, as shown more clearly in Fig. 9.

As before stated, I do not wish to be understood as limiting myself to any particular form or shape of blank, for obviously the general shape and configuration of the blank may vary to suit different demands without departing from the spirit of my invention, the essential feature of which is to provide a box with chamfered or beveled corners and a con tinuous smooth and unbroken outer edge or wall entirely free from projections and the like, such as are usually present in boxes having overlapping portions at the corners.
